Configuring DS3-ATM Cards

Overview of DS3-ATM settings

Parameter

Specifies

Name

Name of the interface. The default value is the interface address in

 

shelf:slot:item format (for example, 1:2:3), but you can assign

 

a text string of up to 16 characters.

Physical-Address Enabled

Physical address of the DS3-ATM port in the TAOS unit.

Enable/disable the DS3-ATM interface. (Disabled by default.) When the interface is disabled, it transmits the DS3 Idle Signal to the far end.

Trunk-Group

Not currently used. Leave the default value (9).

Nailed-Group

Nailed-group number for the DS3-ATM physical interface. A Con-

 

nection or RADIUS profile specifies this number to make use of

 

the interface. Each interface must be assigned a number from 1 to

 

1024 that is unique within the system.

Activation

Line activation mode. Only the static setting is currently sup-

 

ported.

Call-Route-Info Loopback

Not currently used. Leave the default value (the zero address).

Enable/disable loopback for diagnosing connectivity or possible equipment problems. Loopback is disabled by default, which is required for normal operations. For details, see “Looping back the line” on page 14-4.

High-Tx-Output

Framer-Mode

Enable/disable high transmit output. The default is no, which is correct for DS3-ATM cables that are less than 255 feet (78m) long. For cables longer than 255 feet, set this parameter to yes.

DS3-ATM framer mode.Valid values are C-bit-ADMand C-

 

BIT-PLCP(the default). You can specify C-bit Physical Layer

 

Convergence Protocol (PLCP) or C-bit ATM Direct Mapping

 

(ADM) framing format for a DS3-ATM interface. Both sides of a

 

DS3-ATM link must agree about the framing format.

 

The PLCP format incurs some overhead for framing. ADM format

 

does not. When ADM framing is used, the entire DS3 payload is

 

used for ATM cells.

VPI-VCI-Range

Valid range of VCI numbers to be used with specified VPIs for vir-

 

tual channel connections (VCCs). For details about setting the

 

VPI-VCI range, see the APX 8000/MAX TNT/DSLTNT ATM Con-

 

figuration Guide.
